He arrived to Pennsylvania around 1736.
Descendants have long believed that he was the Jacob Chrisman, age 25,
who was on the Pricess Augusta, arriving to Philadelphia on 16 Sep 1736.
However, recent discoveries by researcher Louise Chrisman
have proven that a different Jacob Chrisman,
Jacob "The Moravian", was aboard that
voyage along with his mother, step-father, and several other family
members.
This opens two possibilities. First, previous researchers may have
mistakenly assumed that the Jacob on the Pricess Augusta was him.
A second possibility is that two Jacob Chrismans might have been
aboard the Princess Augusta -- Jacob "the Moravian", at age 16 and being
a minor might not have been listed on the manifest, and Jacob age 25,
who could possibly have been the one who settled in Lehigh Co, PA.
The second possibility, if true, would be suggestive of a close connection
between the two Jacobs.
At the very least, despite earlier claims to this immigration record,
the new information leaves some doubt as to whether this was really
his immigration record.
